EFEITO DO TRATAMENTO HIDROTÉRMICO ASSOCIADO A INDUTORES DE RESISTÊNCIA NO MANEJO DA ANTRACNOSE DA GOIABA EM PÓS-COLHEITA

Abstract

The guava is principally cultivated in tropical and sub-tropical regions. Brazil is one of the principal producers worldwide besides with India, Paquistan, Mexico and Venezuela. The fruit can be used in the industrialization generating many subproducts. The objective of this paper was to evaluate the efficiency of resistance inducers alone and associated with hydrothermal treatment in the control of anthracnose of guava. The fruits that were treated with Agro-Mos® presented minor severity in comparison to the others treatments (Crop-Set, Methyl Jasmonate and Chitosan). The Agro-Mos® was selected to be used associated with the hydrothermal treatment. The temperatures treatments, 47ºC, in any time of exposure and 50ºC in the time exposure of 3 and 6 minutes differs significantly to the others, independently of the association with the inductor.
